Some rebuild advice on a turbo build i picked up - Zilvia.net Forums | Nissan 240SX (Silvia) and Z (Fairlady) Car Forum

I picked a project 240 motors was ran lean had detonation issues. Still checking everything over but I had a few questions. Car has DSM 450cc injectors + T25 turbo + z32 maf + safc. No idea if PO just got greedy and blew the motor but to me this combo seems like plenty of fuel to have decent AFRs. Maybe the guy just advanced the timing to much no idea...

Im not looking for mad power so i wanted to keep everything and run a new block and keep stock ecu and add fuel where needed with the safc. Normally i like to use a standalone and tune myself a lot more easy for me no guess work. I wanted to try a budget build for once so looking for advise on this combo. Any one have any insight if this set up is reasonable or what I should do moving forward on this rebuild?
